Good day, we're receiving a movins file with the following string
the question is: is it acceptable a code like this 40HR or it's better to use normal ISO code (e.g. 45R1)
or asterix if part of the code is unknown ?
About your question: 40HR is a valid "group code" which relates to Thermal containers - refrigerated and/or heated with removable equipment.
This "group code" includes the following "type codes":
H0 Refrigerated and/or heated with removable equipment located externally, coefficient of heat transfer K=0.4 W/(m2.K)
H1 Refrigerated and/or heated with removable equipment located internally
H2 Refrigerated and/or heated with removable equipment located externally, coefficient of heat transfer K=0.7 W/(m2.K)
There is a really detailed documentation on the SMDG web site under the menu SMDG->Documentation->SizeType->New.
